Found these mysterious wires in my Z

Vaibe

I'm pretty sure they're for a previous system that an owner before me took out, can anyone help me figure out what these wires are? I'm really new to car audio so sorry if this seems like a dumb question :x

Going to update this post so people don't have to read through the entire thread. Giving a little background to my situation as well.

So here's my story, I bought this car used a few months ago and I want to put in a system now. I was told my the previous owner that I bought it from, that there may have been a previous system because the tweeters look aftermarket and there were speaker hole cutouts in the carpet. I decided to check around the car today and saw some wires and I think I've figured out what most of the wires are.

First were these wires, http://i.imgur.com/uEvPU0P.jpg, I found them in the trunk tucked away where the foam piece was and I pulled them out from the trunk and put them behind my passenger seat for now. They come from the center console, so I think they're for the Polk DB6501 components to connect to an amp, if someone can verify this that'll be great!

Then there was this, http://imgur.com/a/sgvpD which I and some other forum members believe to be the power wire. It's connected to the battery so I'm pretty sure we've got this one. Someone mentioned something about a fuse inline, do I need that?

Lastly, there was this, http://imgur.com/a/ADE02 and I believe that's the remote turn on wire that hooks up to the HU that detects if it's on and powers on the amp.

Definitely wires from an old system. Probably subwoofer and speaker wire.


Where did you see them?

I saw them behind the passenger seat, tucked away and wired to the back underneath the foam piece in the trunk. I also think I see a ground coming from my battery that I'm going to follow.

Heres a link to my battery:

Don't just yank them out. You can use them to pull your new wires. Or re-use them, if they are long enough.

I haven't yanked them out yet in hopes that I could use them for a new amp/sub. The four wires are currently sitting behind the passenger seat with about two feet of exposed wires.

Edit: I think I found the ground from the battery as well, but it looks cut and electrical tape is covering it. Would this be too short to ground it anywhere?

Hi, your Z color is called platinum graphite.

SouthArk370Z

You don't really need a ground back to the battery - find a nearby spot on the frame/body. Doesn't hurt to run a ground to the battery but you don't gain any thing *if you have* it grounded to the frame properly.

Edit: *over having*

yeah, running back to battery is merely wasting wire.

Okay, a little update.

So I did some more digging about the blue wire from the battery and found that that's the wire that actually goes to the trunk, anyone know what it's for? Some of you guys said that I didn't need a ground from the battery, could I use that as a ground for the amp?

Maybe this is a power wire?

I found one last wire, it's a really thin, long wire (about 1mm in diameter and about 6ft long) and it wasn't connected to anything, just hidden under the trim near the seats and door next to the power wire, anyone know what this wire would be for?

Is this a remote turn on wire?

At this point, I kind of want to buy a new wiring kit. Anyone have some good suggestions for some?

That is a power wire not a ground. And it doesn't appear to have a fuse inline. First thing is to get a fuse installed. Check and make sure it is big enough to feed your equipment. If not, use it to pull your power wire.

You can also re-purpose the wire for grounding. If it's big enough for power, it's big enough for ground. And vice versa.

Possibly a signal wire for something like turning on the amps when the HU is turned on.


BTW, wire doesn't wear out (unless it is abused). If the wire is of sufficient gauge, I'd go ahead and use it.

Thanks so much for the help so far!

How do I check if the wire is sufficient enough to power my equipment? Any good guides you know of?
